Some people emigrated before the return of Hong Kong.

Before Hong Kong's reunification, British people could go to Hong Kong at will, because Hong Kong was a British colony at that time.

Hong Kong has been a territory of China since ancient times, and was once a British colony during 1842- 1997. On July 6th, the China government resumed the exercise of sovereignty over Hong Kong, and the Hong Kong Special Administrative Region was established.

The central government has full power over Hong Kong. Hong Kong has maintained its original capitalist system for a long time, enjoying a high degree of autonomy in all matters except foreign affairs and national defense. It participated in many international organizations and conferences in the name of "China Hongkong". "One country, two systems", "Hong Kong people ruling Hong Kong" and a high degree of autonomy are the basic national policies of the China government.

Post-colonialism refers to the immigrant settlements established by a country in its conquered areas (countries) to obtain new resources for the suzerain country. In the capitalist period, especially in the imperialist stage, it refers to a country or region whose territory is occupied, loses its sovereignty and independence, is completely ruled and dominated by capitalist powers politically and economically, and aims at plundering various resources.

The "constructive mission" of the colony, that is, the positive significance, is usually manifested in the following aspects: the suzerain country exports capital and technology to the colony for construction and provides modern infrastructure such as ports and roads.

The commodity economy in the colonies also developed, the pace of urbanization accelerated, and railways, highways, telecommunications, telephones, hospitals and schools appeared, bringing the originally backward colonial areas into the market economy. A typical example is Hong Kong.
